IMPROVEMENT IN CQRN-SHELLERS- Specification forming partof Letters Patent No. 201,359, dated March 19, 1878 application filed 2 December 31, 1877.

To all whom it may concern Be it known that we, HENRY G. SCHARN- WEBER and EDMUND BARKHAM, of Commerce, in the county of Oakland and State of Michigan, have invented a new and useful Improvement in Oorn-Shellers and we do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and being a part of this specification.

The nature of this invention relates to an improvement in construction of corn-shelling Machines; and it consists in the peculiar manner of vibrating the slotted cob-discharge apron, and in the combination with the same of the carrier-trough and spiral conveyor, as

fully hereinafter explained.

Figure 1 is a perspective view. central longitudinal section.

In the drawings, A represents the frame and case of a sheller surmounted by the hop; p'er B, whose discharge-orifice a is at one end.

Rigidly secured to one end of the frame A is a bracket-frame, G, in the upper girder of which one end of the shaft D is journaled at b, while the other end of the shaft which runs longitudinally through the center of the case is journaled in the frame at c.

Mounted upon this shaft D, within the case, is a cylinder, E, in whose surface are spirally arranged the shelling-teeth 0. These teeth we prefer to make with square heads, and provide them with screw-points, in order that they may be regulated in their projection from the cylinder, as circumstances may require.

Surrounding this cylinder, excepting at the point directly under the discharge-orifice of the hopper, is a shelling-cage, F, which is composed of square bars of iron set so as to present one corner or edge of each bar to the ears of corn as they are thrown against them by the action of the cylinder, and at such distance apart as to prevent an ear of corn passing between them.-

Rigidly' secured to one end of the frame A is a wind-trunk, G, carrying at its top a fancase and an exhaust-trunk, H, an air-passage, h, communicating between the trunk G and Fig. 2 is a fan-case H. The shaft D extends beyond the case A, and through the fan-case and Windtrunk, carrying upon its end a fan-Wheel, I.

Between the wind-trunk G and the case A there is keyed to the shaft D a pulley, d. Directly under this pulley dis another pulley, e, mounted on the end of a carrier-shaft, J, journaled through the frame A, and within a carrier-trough, K, constructed below the main case of the machine. Secured to this shaft J is a spiral carrier, L.

From the discharge end of the carrier-trough there is a spout, M, which connects with the lower end of the Wind-trunk.

There is an opening in the end of the case A, opposite the end of; the shelling cage, through which the cob is ejected. Should there be any kernels of corn still adhering to the cob they will be shaken off by the slotted vibrating apron N, which is pivoted at that end of the machine to the case, and receives its vibrating or jarring motion from a stud or.

knocker, n, upon the end of the carrier-shaft. The corn which is shaken off by this apron falls through the slots or openings down into the carrier-trough.

A pulley is secured to one end of the shaft D, by means of which motion is imparted to the various parts from anyconvenient power.

Corn in the ear is fed into the hopper B and discharged therefrom through the orifice into the shelling-cage and upon the spiked cylinder. This cylinder, being kept continually revolving, throws the ears against the bars of the cage, the result of which is to effectually shell the corn from the ear. The kernels of corn drop to the bottom of the case and into the carrier-trough, from whence they are car ried to the spout M and discharged into the wind-trunk G, falling from thence into a bag or other proper receptacle. Should there be any chaff or small pieces of cob mixed with the corn after being shelled, they are drawn up the wind-trunk by the fan or blower and discharged through its discharge-trunk. The

' cob passes on over the cylinder to the exit at the rear of the machine, and falls upon the vibrating apron, which shakes off what kernels of corn there may be still adhering to it, such cob-discharge apron N projecting from one end of the machine, and vibrated by a knocker, n, upon the end of the conveyer-shaft situated below it, substantially as described and shown.

2. In a corn-shelling machine, the combination of the carrier-trough K, situated longi; V tudinally below the shelling-cylinder and inclosing-cage, and extended at one end beyond,

the same, the spiral conveyer L having its shaft J passing through theiend of the car? rier-trough, with the slotted cob-discharge apron N vibrated by the conveyer-shaft, and

having its slots arranged directly over the extended end of the carrier-trough, constructed and arranged substantially as described and shown.

' In testimony that we claim the above as our invention we hereunto affix our'signatures.
